"They were responding to a complaint from a fan who thought there was an inappropriate display of affection; there was no subjective singling out by the stadium," Hale said. "We take both parties' concerns seriously, but we can't really say anything because we are still investigating exactly what happened. But I do know that we have a policy in place that is meant to be welcoming to all fans, so all fans can enjoy their experience, regardless of race, sexual orientation, physical ability, etc."
The discrimination claim by Guerrero is not the first time Safeco Field has been at the center of same-sex controversy. In 2004, the stadium was the site of a "MAYDAY for Marriage" rally, in which more than 20,000 people turned out to protest same-sex unions.
Julie Oleson, 25, who, along with several other lesbians, was attending the game with Guerrero, said the rally surfaced in her mind immediately.
"It definitely popped into my head, but I'm from Seattle, and there's an anti-discrimination law. It was still very surprising," Oleson said. "The fact that we were approached and singled out at a baseball game …… it was all frustrating. We were enjoying our $10 tickets like everybody else in the nosebleeds."
Oleson, who spoke to the guest services supervisor when the situation between Guerrero and stadium officials continued to escalate, has been equally frustrated with Safeco's handling of the incident since it occurred.
"After the situation escalated and I had had enough, I went to the security captain," Oleson said. "He actually instead was like, 'Is this just kissing? Oh, this is no big deal, just go back to your seats and enjoy the game.' So first it was a problem, then it wasn't problem. It seemed like the supervisor just tried to sweep it under the rug like nothing happened, I guess hoping we would just let it go."
Guerrero and Oleson have spoken to Safeco officials once since the game.
"I talked with a rep from the Mariners who was looking for more clarification," Oleson said. "She gave an apology, but it was hard to figure out who she was apologizing for, like what was behind it, since she didn't say they did anything wrong. I still haven't gotten a definition of what 'inappropriate behavior' is, but I would like to go to a place where it didn't matter."
Melissa Benites, 25, a friend who attended the game with Guerrero, said the couple filed a formal complaint because it was a chance to make a statement for a greater cause.
"It could have been a situation where we just let it go like it wasn't a big deal, but we felt we needed to stand up for ourselves and more importantly, other same-sex couples."
Guerrero, who has appeared on the popular MTV reality show "A Shot at Love 2 With Tila Tequila," agreed. "This is definitely a greater cause," she said. "I'm a firm believer in equal rights, and I want everyone to know what happened to me so it doesn't happen to them in the future."
The results of Safeco's investigation are still to come but the specific behavior will be the deciding factor, said Mariners spokeswoman Hale, questioning whether the couple were only "pecking."
"I've talked to one girl who we asked to characterize the level of behavior, and she admitted it was affectionate kissing," Hale said. "Now I don't know what that means, but it says to me it was something more than just an innocent kiss. All I can say is that we're still investigating and talking to all parties involved."
